What happen to the $1?
-
I want to buy a tee that cost $97, So i Borrow from my mum $50 and from my dad $50,
After i brought the tee, i left with $3, i used $1 to buy green tea and return my mum and dad $1 each, in the end i owe my mum $49 and my dad $49,
BUT then. $49+$49 = $98 ( The total amount i owe)
$98 + $1 (the green tea) = $99.
What happen to the $1?
-
Is this a problem sum ?
-
Can like that say ?
-
lol
well it’s actually 98 + 2 ( the one from your mom and the one from your dad) = 100
if u count with the one left to you it’s 97+3 so it’s still 100 -
There is no missing $1.
100 - 97 = 3
97/2 = 48.50
48.50 X 2 + 1 + 1 + 1 = 100 -
Oh ! I see ! No wonder i can't solve that problem given by my friend ! Thanks !

this is just your own analogy mixing and trying to confuse people.you spend 98dollas, 97 on shirt and 1 on green tea. that is no doubt. 98 divide by two you owe your parents 49 each. period. what's so difficult? you only add herea nd tehre to confuse people only.

Jiani was wrong.... The problem was caused by a erroneous "+1" to $98....
Tee= $97
Borrowed money = 2 x $49 = $98
Borrowed money - Tee cost = $1 which you used to buy green tea.

No, i was asked by my friends and was very confused and want to ask the sgforumers :)

The $1 for the green tea was counted twice.
Should not be borrowed $49 x 2 = $98 ($97 + $1), and then add the $1 again to get $99
Should be $49 x 2 = $98 ($97 + $1). End of the story.
Or $50 x 2 = $100 - $2 = $98 ($97 + $1). End of the story.

same apply to other tih==higns in life. people who continue tokin here and ther does not mena they good toker, its the contents you have to listen carefully. no one is a good talker. but one who knows what he is doing, toalks about what he does best, alwasy perceived as a good toker. so really when i say the thing si do good at, i am not a good talker really. now when i go interview i never prpare myself. come shit will i just answer what i know, what comes to my heart.

Achievement Unlocked: Cannot count, Don't borrow.
Anyways, it's time to prepare yourself should your buddies launch you other mathematical quizzes of doom!
[1] You have 8 perfectly similar-looking eggs. 7 of the eggs are of the exact same weight while 1 of the egg is slightly heavier.
Given a balancing scale and only 3 tries, how can you always determine which one the heavier egg is?
[2] 3 dudes in a room, Ang Mo (A), Bangla (B) and Chinki (C) are presented with 3 black fedora and 2 white fedora. Without looking at the fedora's colours, they randomly pick 1 and equip it on their head.
Now they stand in a line, in the following formation: || Wall || <= A <= B <= C
C can see what A and B's fedora is, B can only see A's fedora and A cannot see anyone's fedora.
C then says "I do not know what colour my fedora is", B also replied "I do not know what colour my fedora is". But A responded, "I know what my fedora's colour is."
What colour fedora is A wearing and how was he able to tell?
[3] You have 10 unlabelled bottles filled with 100 pills each. 9 of the bottles contain pills of 1 gram each while 1 of the bottle contains pills of 1.1 gram each.
You are given a high accuracy weighing scale but you can only use the scale once. You are given the freedom to weigh the bottles/pills separately if required. How can you determine with 1 try, the bottle containing the 1.1 gram pills?
Have fun with the question! -
1) place 3 eggs on each side of scale , if equal, then replace with remaining 2 with one each side. If not equal, take the batch which is heavier and remove the rest. Place 1 each side. Max: 2 tries on scale. :p
2) When C say he dunno means he sees either 2 black fedora or mixed. When B say he dunno means he sees black.
-
3) Mark 1~10 on bottles. Remove 1 pill from bottle1, 2 pills from bottle2, 3 pills from bottle3,... 55pills total. If wt=55.1g, ans:bottle1, if wt=55.2g, ans:bottle2, if wt=55.3g, ans:bottle3,...
